The End of Roman Britain
by Peter Kessler, 30 June 2007
Part 5: Pelagian and pro-Celtic?
Despite the status and wealth of the aristocracy who turned up to meet
Germanus, when being confronted about their Pelagianism by Germanus they
were no match for the Roman's skill at the still effective powers of public
debate, the art of rhetoric in which any Roman gentleman was trained.
Germanus won the crowd over, and defeated the aristocratic arguments. In
fact, it seems that such was the feeling against the nobility that they were
only just saved from the attentions of a violent mob.
Germanus also met 'a man with tribunician power' (vir tribunicae
potestatis) during his visit, and apparently miraculously healed his
blind daughter . Although the use of the word
tribunus as a military rank seems to be extremely loosely used in the
Late Empire, on top of the evidence for the survival of Roman life at
Virulamium, there exists the possibility that this tribune had commanded a
unit of the Roman army which had disbanded after the break with Rome, and
was now occupying a more locally granted appointment to help manage the
Germanus would certainly know a legitimate officer when
he saw one, so his biographer's account, if it hasn't been distorted, should
be believable. However tenuous the connection between the tribune's rank and
his assumed position may be, it remains an enticing possibility.
One wonders about the condition of the city, though.

buildings clearly still stood and were occupied, but some later construction of
much more modest abodes must have taken place. While Germanus was recovering
from a broken leg following his visit to St Alban's shrine and his return
'from this place' (presumably back to Verulamium or Londinium) , 'fire broke out in a cottage [not a
house] near his lodging, and after destroying the adjoining dwellings which
at that place were thatched with reeds from the marshes, it was carried by
the wind to the cottage where he lay.'
If this was indeed
one of the two cities mentioned, the standard of living, at least in this quarter of the city,
had dropped somewhat. It may well be that Germanus elected to reside amongst
peasants or tradesmen rather than reside with those wealthy Pelagians whom he met
earlier, and that the wealthier folk still occupied the Roman heart of the
Religious debate aside, however, defence was still clearly an issue. The
army (or at least an army, in whatever form it
now took) in Britain together with the laeti must have proved too few
in number, too limited in their abilities, or perhaps simply too stretched
in their capacity, to be ale to meet all of the needs that were now required
of them. It seems that the Picts and Saxons had teamed up again to raid the
coast and Germanus took command of the local defence, traditionally at Mold
in North Wales, and managed to see off the raiders.
The fact that he had
to conduct a mass baptism of his troops before the battle suggests that he
was not receiving help from the nobility (many of whom he had very recently
upset) but that his men were mostly from the pagan rural Britons in the
rough Welsh countryside who made up
the farming workforce.
After that victory, Germanus' eventful visit seems to have ended, and he
returned to Gaul.
Battling British politics
Perhaps Vortigern was among the Pelagians who Germanus managed to
verbally defeat during his visit. There certainly seems to have been an
undercurrent of disaffection from the people for the nobles who met
Germanus, and who narrowly escaped a lynching.
If they were part of Vortigern's ruling party then the disaffection would certainly have involved
him to an extent, as it still does whenever something scandalous occurs in
modern British politics. Gildas backs this up by stating that Vortigern was
outflanked in internal British politics. His powerbase might have been far
from reliable by this stage, so perhaps he could also no longer rely on the
military forces at his disposal, especially if some of them had previously
been supplied by Catholic, or pro-Roman, territorial leaders within Britain.
In the year following
Germanus' visit, and in line with standard Roman imperial policy in Gaul,
Vortigern brought in Saxon allies (foederati) to help restore order
on the borders. As with previous deployments of barbarian allies,
they were probably positioned outside various cities in small settlements,
and according to Gildas they did the job for which they were hired. It has already been shown that Germanus himself had to mount
an expedition of his own in 429 to fight off raiding barbarians, but the problem cannot have been
entirely solved - unless we look at the situation from the political angle.
If Vortigern was losing his grip on power, perhaps the mercenaries were
introduced to give him an extra bargaining chip, and some hired muscle if he
required it. This helps paint a picture of Vortigern's power slipping away from
him and his opposition perhaps gaining in strength as a result. If this is
correct then clearly a confrontation was becoming inevitable.
According to what few scraps of evidence remain, the rift between Vortigern's
pro-Celtic faction and that of the pro-Roman Aurelius Ambrosius (Ambrosius
the Elder) erupted into open hostility in circa 437/8. He and Vortigern
fought the battle of Guolloppum (Cat Guolph, identified as Wallop in
Hampshire). Whatever the outcome of the battle, and whatever other action
took place as part of this civil war, it did nothing to strengthen Vortigern's authority, and
political cohesion in Britain even further, as well as weakening its already
overstretched military forces.
Taking advantage of the political turmoil, in circa 440 the Saxon
foederati, almost certainly positioned around the country near the
cities, revolted, ravaging the island from east to west in much the
same way as the Vikings would four hundred years later. During this
catastrophe, the warring British factions probably agreed to temporarily
patch up their differences while they fought a common enemy, but Ambrosius the Elder was killed, and Vortigern struggled
for some time to reassert what little of his authority remained.
For many this was the last straw. Life in western Gaul, in Armorica and
Soissons, would have looked far more stable and settled that it was looking
in Britain, so, due to the social instability caused by this devastating
event, there was a wave of migrations by Britons to Gaul, especially to the
already established British colony in Armorica.
This disastrous period, the first real calamity since the barbarian
attacks of 409, is the probable source of the Britons' appeal for help to Rome
around this time, suggesting that the barbarians were taking advantage of
Roman preoccupations elsewhere. Gildas wrote:
"Again, therefore, the wretched remnant, sending to Aėtius,
a powerful Roman citizen, address[ed] him as follows: - 'To Aėtius, now
consul for the third time: the groans of the Britons.'"
Calamity follows catastrophe
Eventually, order was restored. Those cities which were still inhabited
were repaired and their defences restored. Improvement works were carried
out on some of them and they were cleaned up and restored to a habitable
condition. The population had declined somewhat due to deaths by civil war,
Saxon pillaging, and the flight of many families to Armorica, and there
appears to have been a level of contraction in the proportions of the
inhabited areas of cities, but life went on.
Unfortunately, disaster returned in 446 in the form of serious plague in southern
Britain. Unburied bodies could be found in the streets and more cities were
abandoned. For many who remained their worlds contracted,
with them often living in wooden huts inside the local amphitheatre or
similar Roman buildings, as was the case in Corinum (modern Cirencester).
There, the amphitheatre's entrance was reduced in size, making it more
The picture of urban occupation appears to have been very varied across the country. Some
cities seem to have been abandoned relatively early, either deliberately or
as a result of being sacked during the revolt, or due the plague, while
others continued to survive, if not thrive, well into the fifth century and
This period of partial urban abandonment coincides with evidence of the reuse and refortification of
Iron Age hill forts. Cadbury Congresbury in Somerset started to produce
substantial quantities of Mediterranean pottery at this time, with smaller
amounts also coming from South Cadbury, as local leaders moved their
residences to more protected locations.
Aegidius and Aėtius
Aegidius was elected magister militum in
Gaul under the prefect, Aėtius, in around 450. Later he became chief
minister in Gaul and was an ardent supporter of Majorian, whom he
helped to power. When Majorian lost ground against replacement
prefect, Ricimer, Aegidius rebelled and created a Roman rump state
that became to be known as the Domain of Soissons.
Gildas asserted that the Britons, having been
deprived of Roman military protection after 409, wrote to a "Roman
commander Agitus". While generally being accepted as Aėtius, the
possibility remains that it could be Aegidius.
Such a disastrous decade and the necessity for
reorganisation and recovery that must have followed it clearly put paid to
any thoughts of continuing the civil war, even if there was a new leader to
take over the command of Vortigern's opposition.
A footnote to the religious confrontation in 426 is that Germanus returned to Britain in circa 446/7
to rescue the Catholics from 'certain people' who were again promulgating
the Pelagian heresy. It appears that this was a last hurrah for the
Pelagians. Germanus was able to persuade the populace to embrace the
Catholic faith again, and the Pelagians, who had been banished by common
consent of the Britons, were taken back to the Continent with Germanus.
It may be a
coincidence, but the Pelagian heresy clearly seems to have been at its
strongest while the proposed pro-Celtic faction was in charge. Once
the pro-Romanised faction was again in charge the heresy
seems to have been entirely eradicated. Does this religious alignment of Pelagians against Catholics tie in
with the assumed political alignment in Britain, with the anti-Romans following
anti-Roman methods of worship? It's an intriguing idea which is supported by
the view of the Pelagians in 446 being a last remnant who were then expelled
from the country.
Now apparently almost entirely friendless and probably desperate for new allies, Vortigern would naturally have followed the
normally successful policy of hiring more foederati to bolster his
flagging command, the fact that the last group had caused so much damage
On the Continent, Aėtius had done precisely the same thing
on a much bigger scale when he settled the Burgundians in Savoy in 443. In
Britain there was probably little immediate threat of a renewal of the civil
war to further threaten his dubious position, so it probably seemed like a good idea at the
time. The fact that these new allies would turn on him in the worst possible
way may not even have occurred to him, although he does seem to have changed
tactics in settling them, taken the precaution of keeping them well away
from any British cities by allotting them land on an island.
Either way, the
'Adventus Saxonum' revolt of circa 450 was worse than the short-lived
pillaging of a decade previously. Kent was quickly lost and a Germanic
kingdom formed there. Vortigern seems to have lost what
little support remained to him and when, in circa 455, Ambrosius
Aurelianus, the presumed son of Ambrosius the Elder, returned to Britain
from Armorica to chase Vortigern out of office, he apparently had little
trouble doing this.
Leaving Roman knowledge
The pro-Romans had won, although the Britain they now controlled was a
very different one from that of 409.
Either way, this can be taken as a point at which Britain left Roman knowledge and
contact almost completely. While the Roman way of life had continued fairly
smoothly between 409 to about 437, the subsequent civil war, foederati
rebellion, plague, emigration, and the loss of east coast territory,
all signalled a significant change in the way British society would survive
in the future, with the emphasis on Romanisation, and even finding the
resources to maintain it, no longer being something that could be indulged.
Brief mentions show that a possible central
administration of some kind continued for perhaps the next half a century or so,
and that it was following the Catholic faith until at least 480 (according
However, even by the middle of the fifth century, the Roman way of life
in Britain was
becoming a fading memory.
